By-right

By-right is a term from American building law. It describes construction projects that an authority must approve as soon as all prescribed rules are met. There is then no city council vote and no hearing at which neighbors can kill the project. The administration only checks whether height, setbacks, use type and similar requirements are correct. If everything fits, the building permit is granted. The counterpart is the discretionary process: there, an elected commission can reject a project even if it is legally flawless.

Why data centers brought this word into tech news

Artificial intelligence needs enormous buildings full of computers, so-called data centers. Companies like Microsoft, Google, Amazon and Meta are investing three-digit billion-dollar sums for this. The bottleneck is often not the money and not even the technology, but the time until approval.

A discretionary process can take two to five years in the US. Citizens' initiatives sue over power consumption, the water consumption of cooling, or the noise of ventilation systems. If a property, on the other hand, is cleared by-right for data centers, a few months are possible. For a company in the race for AI capacity, this difference is enormous.

That is why individual US states are now actively advertising by-right regulations. They write into their zoning plans that data centers are permitted in certain industrial areas without a case-by-case review. Anyone following the stocks or site decisions of the big tech companies encounters the term precisely for this reason.

Rule-checking instead of political vote

The basis is always a zoning plan, called zoning code in English. It specifies for each property what may be built there. An example: In one area, commercial buildings up to 15 meters in height with a 20-meter setback from the property line are permitted. Anyone planning exactly that builds by-right.

The decisive point is that the review runs mechanically. A case officer compares the submitted plans with a list of requirements. It is about measurable quantities, not about taste or political mood. If the application meets everything, the developer has a legal right to the permit.

A common misconception is that by-right means building without rules. The opposite is true: the rules are strict, but known in advance and the same for everyone. Anyone who wants to build even one meter higher leaves the process. Then they need a variance, and that is again decided at discretion.

From Virginia to the debate about German approvals

The best-known case is Loudoun County in the US state of Virginia. It has the highest density of data centers in the world; a significant share of global internet traffic runs through this region. One reason for this is zoning plans that permitted such facilities by-right for years. Residents are now pushing back, and the municipality has partly tightened the rules.

The term also appears outside the tech industry. In California, by-right construction was introduced to combat the housing shortage. If a city builds too few housing units, it loses the right to politically reject suitable projects. The idea is the same: those who comply with the rules should not have to wait for years.

In Germany there is no literal counterpart, but a similar logic. Section 30 of the Federal Building Code (Baugesetzbuch) provides that a project is permissible if it conforms to the zoning plan. In practice, however, environmental reviews and participation procedures are often added. When business news complains about approvals for power grids, wind turbines or server farms being too slow, this is exactly the difference being referred to.
